Problems getting data from the Power BI Service connection

Hi,

I'm a pro user and am definitely using the same user details!

The datasource I'm struggling with is the new one in beta, to connect PowerBI Desktop to the PowerBI Service. In our PowerBI Service we have a shared dataset in a group (that I have edit rights to) that I would like to connect to and make reports on, but when trying to connect to this I receive the errors I originally raised.

For me, I am a Pro User and connecting via web data source (wiki).  I have also tried SharePoint Online data source with the same error.  Here is the trace I ran with the error that was thrown:
